Excellent feedback. All of my switches support PoE+ so I know I am good there, plus they are all Cisco and CDP should be in harmony between the AP and the switch. I may try the pre-802.3af checkbox to see if that does anything as well. Tonight I am performing my PI 2.2.1 backup and will restore to PI 3.0 tomorrow. Thanks for your help with this. It is good to know many others are experiencing the same issue.

Critical Alarms on PI 2.0 for the AP radio, with the message "Administratively UP and Radio Down". This is behavior is CSCup98951 seen even for an AP that is Admin down.

If they are not getting enough power the radio will be up administratively sine you did not disable, but will be down operationally because there is not enough power. Go to the AP on the controller and look at the Advanced tab, in the upper right there is Power Over Ethernet Settings. If the power injector or switch is Pre-standard 802.3af switches check the box. For the AP to Power Injector State check the box. For Power Injector Selection either choose Installed, or if you know the injector has more than enough power choose Override to force the radios on. If you choose Installed, you should see the power inject MAC appear and the AP should be able to communicate with the power inject to see how much power is available.

I have been getting a slew of these lately. We have introduced quite a few 1702's into our environment and I am wondering if there is some issue with recalculation, or something that triggers a radio reset to resolve a different issue? Below is the alert notification. Cisco forums haven't been much help, so I figured I'd take a shot at the group. Thanks!
